RF3417D

Overview

The RF3417D is a surface-acoustic-wave (SAW) filter manufactured by RFMi, designed for front-end selectivity in 315.0 MHz applications. It operates within a frequency range of 314.85 MHz to 315.15 MHz with a bandwidth of 600 kHz. The component features an insertion loss of 1.6 dB and supports a voltage rating of 12 V. Impedance values are specified as 1.92 kOhms and 1.28 kOhms. It utilizes SMD/SMT termination types in an SM-3030-6 package. The device functions reliably between -40°C and +125°C and meets AEC-Q200 qualification standards.

Feature Summary

• Provides front-end signal selectivity for remote keyless entry systems at 315 MHz
• Compact surface-acoustic-wave design suitable for space-constrained board mounting
• Automotive-grade reliability certified under AEC-Q200 standards

Applications

• Remote Keyless Entry (RKE) systems
• Front-end filtering in 315 MHz transmitters
• Wireless access control receivers

Procurement Notes

Verify the specific impedance configuration required for your circuit design, as sources indicate variations such as 1.92 kOhms and 1.28 kOhms. Confirm the package type matches your PCB footprint requirements, noting references to both SM-3030-6 and similar SMD formats. Ensure compatibility with your operating temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component when designing 315 MHz receiver stages requiring high selectivity and low insertion loss. Consider its automotive qualification if deploying in vehicle environments. Evaluate the impedance match against your antenna or amplifier interface to ensure optimal signal transfer without additional matching networks.
